1
Cancer Historically agents given systemically – Agents that kill rapidly dividing cells Find therapeutic dose Kills tumor cells w/o killing patient – Lots of side effects Localized/targeted delivery is the holy grail – Nanomedicine!! – Also protection from degradation and increased solubility
3
Nanoparticles – drug throughout Nanocapsules – drug w/in coating PEGylation – makes stealthy Ligand – binds to cell receptor for targeting
4
Tumor Vasculature Irregularly shaped, big, and leaky Lack of lymph drainage High vessel density
5
Passive Targeting EPR Small drugs enter tumor and leave Particles enter and stay – Long circulation time key
6
Active Targeting EPR + something that binds tumor cells specifically
7
Targeting Interfere with signaling when bind (targeting ligand and drug) Ab tethered to drug Ligand + drug depends upon over-expression of surface molecules by tumor cells
